Clinical Trial Summary

The present investigation is designed as a single-blind, randomized, controlled, bicentric trial. The objective is to ascertain whether the subcutaneous administration of enoxaparin sodium for prophylactic anticoagulation during transradial hepatic arterial infusion chemotherapy (HAIC) can diminish the incidence of radial artery occlusion (RAO) post-procedure


Description:

Primary liver cancer ranks sixth globally in incidence and fourth in mortality, with over 800,000 new cases annually . Hepatocellular carcinoma (HCC) accounts for over 80% of primary liver cancers. Due to its insidious onset, most patients present with intermediate to advanced stage disease at diagnosis and are ineligible for curative treatments such as surgical resection or liver transplantation. For unresectable liver cancer, a combination of locoregional therapies (e.g., transarterial chemoembolization, hepatic arterial infusion chemotherapy) and systemic treatments (e.g., targeted therapy, immunotherapy) constitute the standard care. Hepatic Arterial Infusion Chemotherapy (HAIC) delivers high concentrations of chemotherapy agents directly to the tumor via the hepatic artery, leading to more effective tumor cell kill and suppression. Recent advances in HAIC using the FOLFOX regimen (oxaliplatin, fluorouracil) for intermediate and advanced HCC have been made by researchers in China . However, HAIC typically requires long infusion times. Traditional HAIC involves arterial sheath and catheter placement via the femoral artery, necessitating bed rest for 24-48 hours post-operation, reducing patient comfort, and increasing the risk of deep vein thrombosis in the lower limbs due to prolonged immobilization . Recently, the transradial approach for peripheral intervention has gained attention. Transradial HAIC is favored in clinical practice as it does not require postoperative immobilization or carry the risk of causing deep vein thrombosis in the lower limbs. Radial artery occlusion (RAO) is the most common complication following transradial interventions, often asymptomatic and diagnosed via radial artery ultrasound. The incidence of RAO post-transradial coronary interventions is reported to be between less than 1% to 33% . Preventive measures for RAO typically include: using catheters of the appropriate size (sheath diameter should be less than the radial artery lumen); intraoperative use of unfractionated heparin, short-term postoperative oral anticoagulation; patent hemostasis and shorter compression times . Transradial HAIC is a relatively new practice with limited research. A recent domestic study indicated that the incidence of RAO following transradial FOLFOX-HAIC was as high as 35%, potentially related to prolonged sheath placement and multiple procedures. Retrospective and prospective analyses suggest that the use of low molecular weight heparin during infusion may reduce the incidence of RAO postoperatively . While prophylactic anticoagulation is standard for patients at high risk of venous thromboembolism, it is not typically administered to low-risk patients. Hence, the potential of enoxaparin sodium for prophylactic anticoagulation during transradial HAIC to reduce RAO incidence warrants further investigation. RAO can preclude the possibility of future transradial interventions, impacting the patient's options for intervention access and treatment strategy. Thus, preventing RAO following transradial HAIC has significant clinical importance. This study aims to explore the efficacy of prophylactic enoxaparin sodium in preventing postoperative RAO through a randomized controlled trial. Case Number and Grouping Method: This study plans to recruit 156 subjects and will use a 1:1 randomization to divide them into an experimental group and a control group. Participant Data Collection and Randomization: Data will be collected from subjects on radial artery Doppler ultrasound, coagulation function, and complete blood count within one week prior to receiving trans-radial FOLFOX-HAIC. Those who meet the inclusion criteria will be randomized into the experimental group or the control group in a 1:1 ratio. Specifically, each participant will be assigned a unique identification code, and a random number generator will be used for random allocation to the different treatment groups. This process will be computerized, unpredictable, and uncontrollable, ensuring an equal probability of assignment to each group, known as "randomization." The study will be blind to the subjects. For anticoagulation during trans-radial HAIC chemotherapy, there are no unified clinical guidelines on whether routine prophylactic anticoagulation is necessary. Enoxaparin sodium is a commonly used clinical anticoagulant for the prevention and treatment of thromboembolic disorders, including deep vein thrombosis. Past research has suggested that the use of enoxaparin sodium during HAIC may reduce the incidence of postoperative RAO (Radial Artery Occlusion). After the trans-radial HAIC treatment and catheter removal, subjects in the experimental group will be administered subcutaneous enoxaparin sodium injections at a dose of 4000 Axa IU once daily, while the control group will receive an injection of a placebo (0.9% saline solution) of equal volume once daily. After sheath removal, compression will be applied for two hours before being relieved. During the treatment with low-molecular-weight heparin, patients will be closely monitored for any signs of bleeding, such as from the skin, mucous membranes, gum bleeding, or black stools. On the first day after the procedure, routine blood counts and coagulation function will be checked. Radial artery Doppler ultrasounds will be performed 24 hours later and again after 21 days to assess for the occurrence of RAO. In case of RAO, anticoagulant therapy will be administered promptly.
